The Kardashian family drama is shrouded in mysteries. But, if there’s one dark, dirty rumor that simply fails to die down, it has got to be the speculations surrounding who Khloe’s real dad is.

Khloe, 32, seems unperturbed by what haters and grapevine have to say and holds the late Robert Kardarshian Sr. in high regard. But, does that take away from the fact that there could indeed be a great deal of hidden truth behind Khloe’s paternity? Could O.J Simpson be the real dad? Or better yet, was Khloe the love child, which resulted from a torrid affair that ensued between Kris and her hairdresser?

In all honesty, Khloe doesn’t look anything like her other siblings—she’s taller, with more prominent features and visibly lighter hair and skin tone. History is also laden with instances (and um, real people like the late Robert’s ex-wife Ellen Pierson) supporting the theory.

While the Kardashian sisters slammed Pierson for “spreading lies” in return of some fast cash, Pierson allegedly opened up about the “truth” to a media outlet. “I am simply stating the facts and the truth — their father’s truth,” she said. Yet, time and again, OJ Simpson, as well as the Kardashians, have quelled the speculations. Joni Migdal, a close family friend of the Kardashians also maintained that Robert was convinced that Khloe was not his, but was willing to father her with open arms.

Despite these denials, the grapevine has it that Khloe’s “blood father” could be someone else— Former soccer player Todd Waterman and Alex Roldan are some of the other famous suspects.

Things got a LOT awkward after fans merged pictures of Jenner’s hairdresser Alex Roldan and Khloe. And the similarities in the facial features were uncanny. The world was shook went Kylie Jenner decided to take things up a notch and tweeted about the same— “First official photo of my sister and her dad! Like father like daughter!” she tweeted. And well, everyone knows that Kris was accused of adultery during her marriage to Robert, before it ended in a divorce in 1991.

The Kardashians are a close-knit family, and they really don’t give much importance to the snarky rumors surrounding their lives—not even the eerie decades-old rumor around who Khloe’s real dad is. In 2012, Kris egged Khloe on to get a DNA test to put rumors to rest. But, Khloe seemed far from interested as she opined that she didn’t need anyone to tell her who her family is.

Despite what the truth could be, Khloe loves her late father Robert Kardashian Sr. It is said that the late Robert was so kind and giving, Khloe really doesn’t think there’s anyone else who could fill up the position better than him. Khloe’s also got great affection for her other stepdad, Caitlyn Jenner formerly Bruce Jenner.
